The continents agricultural systems are increasingly disrupted by rising temperatures, erratic rainfall, and extreme weather events, exacerbating hunger, poverty, and rural vulnerability. At the same time, Artificial Intelligence (AI) presents transformative potential to support climate adaptation, improve agricultural resilience, and enhance food systems governance across Africa. This study undertakes a qualitative content analysis and critical synthesis of 25 peer-reviewed articles, institutional reports, and working papers to examine how AI is currently applied and could be more effectively leveraged for climate-resilient agriculture and food security on the continent. Findings reveal a growing body of innovations, from AIdriven weather forecasting and early warning systems to precision agriculture and supply chain optimization. Yet the study identifies persistent structural limitations, including unreliable data infrastructure, low digital capacity in rural areas, and governance gaps around ethical deployment, data ownership, and equitable access. Through African case studies, the paper explores how localized AI solutions when supported by inclusive policies, multi-stakeholder collaboration, and responsible innovation frameworks can mitigate climate-induced food shocks and drive sustainable development. The paper argues for a strategic alignment between AI deployment and national adaptation plans, emphasizing the need for stronger public-private partnerships, investments in AI-ready infrastructure, and the development of ethical and contextsensitive governance mechanisms. In doing so, it offers a roadmap for policymakers, development agencies, and researchers seeking to harness AI not just as a technological tool, but as a catalyst for systemic transformation in African food systems in the era of climate change.","非洲正处在21世纪两大决定性挑战的交汇点：气候变化与粮食不安全。随着气温上升、降雨异常和极端天气事件频发，非洲大陆的农业系统日益受到扰乱，饥饿、贫困和农村脆弱性问题不断加剧。与此同时，人工智能（AI）展现出变革性潜力，可支持非洲的气候适应、提升农业韧性并改善粮食系统治理。本研究对25篇同行评审论文、机构报告和工作论文进行了定性内容分析与批判性综合，考察AI当前在非洲大陆的应用方式，以及如何更有效地将其用于气候韧性农业和粮食安全。研究发现，相关创新不断涌现，涵盖AI驱动的天气预报和预警系统、精准农业以及供应链优化等领域。然而，研究也识别出持续存在的结构性制约，包括数据基础设施不可靠、农村地区数字能力薄弱，以及围绕伦理部署、数据所有权和公平获取的治理缺口。通过非洲案例研究，本文探讨了在包容性政策、多利益相关方协作和负责任创新框架支持下，本地化的AI解决方案如何能够缓解气候引发的粮食冲击并推动可持续发展。本文主张将AI部署与国家适应计划进行战略对接，强调需要加强公私伙伴关系、投资于AI就绪型基础设施，并建立合乎伦理且情境敏感的治理机制。由此，本文为政策制定者、发展机构和研究人员提供了一份路线图，旨在气候变化时代将AI不仅作为技术工具，更作为非洲粮食系统系统性转型的催化剂加以利用。",null,"INTERNATIONAL JOURNAL OF AGRICULTURE AND EARTH SCIENCE","2026-09-16T00:00:00Z","论文",10,false,76,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},18,20,17,13,8,1,"系统综述25篇文献，梳理AI在非洲气候韧性农业中的应用与治理缺口，对农业信息化有参考价值，但属境外区域研究，公共影响有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"智慧农业","农业人工智能","粮食安全","非洲农业","气候适应",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"A8","yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[39],{"code":40,"slug":41,"name":42,"path":43,"parent_code":44},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":46,"locked":14,"version":47,"method":48,"evidence":49},"classified","2026-10-22.2","rules",{"candidates":50,"agricultural_evidence":52},[51,58,64,72,79],{"code":40,"score":17,"supported":52,"title":53,"abstract":55,"tags":57},true,[54],"climate change",[56,31,54],"气候变化",[31],{"code":33,"score":59,"supported":52,"title":60,"abstract":62,"tags":63},15,[61],"food security",[29,61],[29],{"code":65,"score":66,"supported":52,"title":67,"abstract":68,"tags":71},"I1",7,[],[69,70],"精准农业","precision agriculture",[27],{"code":73,"score":74,"supported":52,"title":75,"abstract":76,"tags":78},"I2",4,[],[77],"artificial intelligence",[28],{"code":80,"score":22,"supported":14,"title":81,"abstract":82,"tags":83},"J3",[],[],[30],[85,86],"非洲 农业人工智能 粮食安全","AI 气候韧性农业 非洲","非洲农业人工智能粮食安全-2939",5,"10.56201\u002Fijaes.vol.11.no9.2025.pg79.102",{"doi":89,"openalex_id":91,"authors":92,"venue":10,"cited_by_count":95,"oa_url":96,"card":97,"direction":103,"ingested_from":104},"W7213462904",[93],{"name":94,"orcid":9},"Izuchukwu Adamaagashi",0,"https:\u002F\u002Fiiardjournals.org\u002Fget\u002FIJAES\u002FVOL. 11 NO. 9 2025\u002FClimate Change and Food Security 79-102.pdf",{"tldr":98,"method":99,"finding":100,"direction":101,"opportunity":102},"通过定性分析25篇文献，探讨如何负责任地利用AI推动非洲气候适应型农业与粮食安全。","对25篇同行评议论文、机构报告和工作论文进行定性内容分析与批判性综合。","AI在天气预报、精准农业等方面有创新，但面临数据基础设施差、农村数字能力低和治理缺口等结构性限制。","农业人工智能与决策模型","可研究非洲本地化AI解决方案的伦理治理框架与公私合作模式，填补数据所有权和公平获取的研究空白。","智慧农业 \u002F 农业物联网","openalex","2026-09-19T23:30:19.482449Z",{"total":107,"page":22,"page_size":107,"items":108},6,[109,178,284,379,508,592],{"id":110,"title":111,"url":112,"summary":113,"summary_zh":114,"content":9,"source_name":115,"source_url":112,"published_at":116,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":117,"score_detail":118,"sources":121,"tags":123,"primary_topic":126,"secondary_topics":127,"classification":135,"search_phrases":159,"slug":162,"view_count":22,"doi":163,"paper":164,"created_at":177},5308,"Geopolitics and food security: A comprehensive review of emerging risks and responses","https:\u002F\u002Fdoi.org\u002F10.51200\u002Fjsffs.v2i2.7666","This review paper examines the relationship between geopolitics and food security through a Systematic Literature Review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. A total of 15 peer-reviewed journal articles published between 2015 and 2026 were reviewed to identify emerging geopolitical risks and responses affecting global food systems. The study synthesizes literature on armed conflicts, trade restrictions, climate change, supply chain disruptions, energy market instability, and technological transformation in agriculture. The findings identified four major themes. First, geopolitical conflicts and protectionist trade policies significantly disrupt global food supply chains and increase food price volatility. Second, climate-related shock such as droughts, floods, and extreme weather events intensifies food insecurity, particularly in import-dependent and developing economies. Third, weaknesses in global logistics and energy dependence expose food systems to external shocks and market instability. Fourth, technological innovations, including smart farming, precision agriculture, and digital monitoring systems, play an increasingly important role in strengthening agricultural productivity, improving resource efficiency, and enhancing resilience against geopolitical and environmental uncertainties. The policy implications of this study include strengthening regional food reserves, diversifying import sources, investing in climate-resilient agriculture, promoting the adoption of smart farming technologies, and enhancing institutional cooperation between governments and international organizations. The relevance of smart farming is increasingly evident, as precision agriculture, Internet of Things (IoT)-based monitoring systems, and data-driven farming technologies play a critical role in improving productivity, reducing resource inefficiency, and enhancing food system resilience under geopolitical stress. The study contributes to a broader understanding of how geopolitical dynamics shape food security and provides recommendations for building sustainable, resilient, and technology-driven food systems in an increasingly uncertain global environment.","本文通过遵循系统评价与荟萃分析首选报告条目（Preferred Reporting Items for Systematic Reviews and Meta-Analyses）框架的系统文献综述，考察地缘政治与粮食安全之间的关系。共 review 了2015年至2026年间发表的15篇同行评审期刊论文，以识别影响全球粮食系统的新兴地缘政治风险与应对措施。本研究综合了关于武装冲突、贸易限制、气候变化、供应链中断、能源市场不稳定以及农业技术转型的文献。研究结果识别出四大主题。第一，地缘政治冲突和保护主义贸易政策显著扰乱全球粮食供应链并加剧粮食价格波动。第二，干旱、洪水和极端天气事件等气候相关冲击加剧粮食不安全，尤其是在依赖进口的经济体和发展中经济体中。第三，全球物流的薄弱环节和能源依赖使粮食系统暴露于外部冲击和市场不稳定之中。第四，包括智慧农业、精准农业和数字监测系统在内的技术创新，在增强农业生产力、提高资源效率以及增强应对地缘政治和环境不确定性的韧性方面发挥着日益重要的作用。本研究的政策启示包括加强区域粮食储备、多元化进口来源、投资气候韧性农业、促进智慧农业技术的采用，以及加强政府与国际组织之间的制度合作。智慧农业的相关性日益明显，因为精准农业、基于物联网（IoT）的监测系统和数据驱动农业技术在提高生产力、减少资源低效以及增强地缘政治压力下粮食系统韧性方面发挥着关键作用。本研究有助于更广泛地理解地缘政治动态如何塑造粮食安全，并为在日益不确定的全球环境中构建可持续、有韧性且技术驱动的粮食系统提供建议。","Journal of Smart Farming and Food Security","2026-10-19T00:00:00Z",77,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":119,"relevant":22,"comment":120},9,"系统综述梳理地缘政治与粮食安全风险，并强调智慧农业的韧性价值，具政策与产业参考意义，但属综述性论文，非突破性成果。",[122],{"name":115,"url":112},[27,124,29,69,125],"农业供应链","地缘政治",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[128,129],{"code":40,"slug":41,"name":42,"path":43,"parent_code":44},{"code":130,"slug":131,"name":132,"path":133,"parent_code":134},"I5","agricultural-iot","物联网传感与边缘计算","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-iot","I",{"status":46,"locked":14,"version":47,"method":48,"evidence":136},{"candidates":137,"agricultural_evidence":52},[138,142,147,152],{"code":33,"score":59,"supported":52,"title":139,"abstract":140,"tags":141},[61],[29,61],[29],{"code":65,"score":143,"supported":52,"title":144,"abstract":145,"tags":146},11,[],[27,69,70],[27,69],{"code":40,"score":119,"supported":52,"title":148,"abstract":149,"tags":151},[],[56,150,54],"干旱",[],{"code":130,"score":119,"supported":52,"title":153,"abstract":154,"tags":158},[],[155,156,157],"物联网","internet of things","IoT",[],[160,161],"地缘政治 粮食安全","智慧农业 粮食系统韧性","地缘政治粮食安全-5308","10.51200\u002Fjsffs.v2i2.7666",{"doi":163,"openalex_id":165,"authors":166,"venue":115,"cited_by_count":95,"oa_url":112,"card":172,"direction":103,"ingested_from":104},"W7222902031",[167,169],{"name":168,"orcid":9},"Parameswaran Mahendran",{"name":170,"orcid":171},"Wong Sing Yun","https:\u002F\u002Forcid.org\u002F0000-0001-5776-8852",{"tldr":173,"method":174,"finding":175,"direction":103,"opportunity":176},"系统综述地缘政治风险对粮食安全的影响及应对，强调智慧农业的韧性作用。","按PRISMA框架系统综述2015-2026年15篇同行评议文献。","冲突、贸易限制、气候与能源冲击威胁粮食安全，智慧农业可提升韧性与效率。","可量化研究物联网与精准农业在地缘政治冲击下对粮食系统韧性的实证贡献。","2026-10-19T23:30:07.850994Z",{"id":179,"title":180,"url":181,"summary":182,"summary_zh":183,"content":9,"source_name":184,"source_url":181,"published_at":185,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":186,"score_detail":187,"sources":190,"tags":192,"primary_topic":195,"secondary_topics":196,"classification":204,"search_phrases":250,"slug":253,"view_count":21,"doi":254,"paper":255,"created_at":283},3169,"Climate change and the rising threat of Macrophomina phaseolina: implications for food security, food safety, and sustainable crop health management","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs10725-026-01525-5","Abstract Macrophomina phaseolina is a destructive soil-borne necrotrophic fungal pathogen that causes substantial yield losses in a wide range of economically important crops worldwide. Disease severity is strongly enhanced under drought, high temperature, and salinity stress, conditions that are becoming increasingly prevalent under current climate change scenarios. This review examines the interactions between climate-driven abiotic stress, host physiological regulation, and pathogen aggressiveness, highlighting how stress-induced disruptions in hormonal signalling, reactive oxygen species homeostasis, antioxidant defence systems, and plant metabolism collectively increase susceptibility to M. phaseolina . Recent advances in understanding pathogen virulence mechanisms, plant immune responses, and resistance-associated molecular pathways are synthesised together with emerging evidence from transcriptomics, proteomics, metabolomics, and comparative genomics. The review further evaluates current management strategies, including host resistance, biological control, plant growth-promoting microorganisms, stress priming, and integrated disease management, while discussing their limitations under field conditions. Emerging technologies such as precision agriculture, remote sensing, artificial intelligence-assisted disease forecasting, and multi-omics approaches are highlighted as promising tools for improving early diagnosis, risk prediction, and climate-resilient disease management. By integrating advances in plant physiology, molecular biology, and sustainable crop protection, this review provides a comprehensive framework for understanding M. phaseolina pathogenesis under changing environmental conditions. It identifies key research priorities to improve crop resilience and safeguard global food security.","摘要 菜豆壳球孢（Macrophomina phaseolina）是一种具有破坏性的土传死体营养型真菌病原菌，在全球范围内对多种具有重要经济价值的作物造成严重产量损失。在干旱、高温和盐胁迫条件下，病害严重程度显著加剧，而这些条件在当前气候变化情景下正变得越来越普遍。本文综述了气候驱动的非生物胁迫、寄主生理调控与病原菌致病力之间的相互作用，重点阐述了胁迫诱导的激素信号传导紊乱、活性氧稳态失衡、抗氧化防御系统受损以及植物代谢改变如何共同增加对菜豆壳球孢的易感性。本文综合了病原菌毒力机制、植物免疫反应及抗性相关分子通路方面的最新研究进展，并结合转录组学、蛋白质组学、代谢组学和比较基因组学的新兴证据。本文进一步评估了当前的管理策略，包括寄主抗性、生物防治、植物促生微生物、胁迫 priming 和病害综合管理，同时讨论了这些策略在田间条件下的局限性。精准农业、遥感、人工智能辅助病害预测和多组学方法等新兴技术被重点介绍为改善早期诊断、风险预测和气候韧性病害管理的有前景的工具。通过整合植物生理学、分子生物学和可持续作物保护方面的进展，本文为理解变化环境条件下菜豆壳球孢的致病机制提供了综合框架，并确定了提高作物韧性和保障全球粮食安全的关键研究优先方向。","Plant Growth Regulation","2026-09-22T00:00:00Z",80,{"impact":17,"substance":18,"depth":17,"authority":188,"freshness":13,"relevant":22,"comment":189},14,"核心期刊综述，系统梳理气候胁迫下土传病害机制与AI遥感等智慧防控手段，对农业信息化与粮食安全主题有聚合价值。",[191],{"name":184,"url":181},[27,29,193,56,194],"植物病害","遥感监测",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[197,198],{"code":40,"slug":41,"name":42,"path":43,"parent_code":44},{"code":199,"slug":200,"name":201,"path":202,"parent_code":203},"E4","food-safety","质量安全与溯源","\u002Ftopic\u002Ffood-supply\u002Ffood-safety","E",{"status":46,"locked":14,"version":47,"method":48,"evidence":205},{"candidates":206,"agricultural_evidence":52},[207,212,216,221,225,232,239,246],{"code":40,"score":17,"supported":52,"title":208,"abstract":209,"tags":211},[54],[56,150,54,210],"drought",[56],{"code":33,"score":59,"supported":52,"title":213,"abstract":214,"tags":215},[61],[29,61],[29],{"code":199,"score":21,"supported":52,"title":217,"abstract":219,"tags":220},[218],"food safety",[],[],{"code":65,"score":66,"supported":52,"title":222,"abstract":223,"tags":224},[],[69,70],[27],{"code":226,"score":66,"supported":52,"title":227,"abstract":228,"tags":231},"I3",[],[229,230],"遥感","remote sensing",[194],{"code":233,"score":107,"supported":52,"title":234,"abstract":235,"tags":238},"F4",[],[236,237],"生物防治","crop protection",[],{"code":240,"score":241,"supported":52,"title":242,"abstract":243,"tags":245},"H2",3,[],[244],"soil",[],{"code":73,"score":241,"supported":52,"title":247,"abstract":248,"tags":249},[],[77],[],[251,252],"Macrophomina phaseolina 病害 防控","气候变暖 土传病害 粮食安全","Macrophominaphaseolina病害防控-3169","10.1007\u002Fs10725-026-01525-5",{"doi":254,"openalex_id":256,"authors":257,"venue":184,"cited_by_count":95,"oa_url":181,"card":277,"direction":282,"ingested_from":104},"W7213972258",[258,260,262,265,268,271,274],{"name":259,"orcid":9},"Sindiswa Khawula",{"name":261,"orcid":9},"Siyabonga Ntshalitshali",{"name":263,"orcid":264},"Arun Gokul","https:\u002F\u002Forcid.org\u002F0000-0003-1575-0632",{"name":266,"orcid":267},"Lee‐Ann Niekerk","https:\u002F\u002Forcid.org\u002F0000-0002-9788-3131",{"name":269,"orcid":270},"Ashwil Klein","https:\u002F\u002Forcid.org\u002F0000-0002-5606-886X",{"name":272,"orcid":273},"Marshall Keyster","https:\u002F\u002Forcid.org\u002F0000-0002-8718-736X",{"name":275,"orcid":276},"Mbukeni Nkomo","https:\u002F\u002Forcid.org\u002F0000-0002-7652-1588",{"tldr":278,"method":279,"finding":280,"direction":101,"opportunity":281},"综述气候变化下干旱高温盐胁迫加剧菜豆壳球孢菌病害的机制与可持续防控策略。","整合转录组、蛋白组、代谢组、比较基因组及精准农业、遥感、AI预测等技术。","气候胁迫破坏激素与ROS平衡降低作物抗性，需多组学与智能技术实现早期预警和抗性管理。","可构建融合多组学与气象遥感的AI病害预警模型，并研发胁迫 priming 与生防协同的田间方案。","农业遥感与作物表型","2026-09-22T23:30:22.790623Z",{"id":285,"title":286,"url":287,"summary":288,"summary_zh":289,"content":9,"source_name":290,"source_url":287,"published_at":291,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":15,"score_detail":292,"sources":294,"tags":296,"primary_topic":300,"secondary_topics":301,"classification":308,"search_phrases":362,"slug":365,"view_count":88,"doi":366,"paper":367,"created_at":378},3156,"Climate Adaptation and Sustainable Agriculture in Africa: Strategies for Food Security","https:\u002F\u002Fdoi.org\u002F10.56201\u002Fijgem.vol.11.no2.2025.pg8.32","This study investigates the role of Climate-Smart Agriculture (CSA) and agroecology in enhancing agricultural resilience and food security in the face of climate change in Africa. Through a comprehensive review of existing literature, case studies, and policy frameworks, the research explores how these adaptive strategies are being implemented across the continent and assesses their effectiveness. The findings reveal that while CSA techniques—such as droughtresistant crop varieties, water-efficient irrigation, and soil management practices—offer tangible benefits to agricultural productivity and resilience, their widespread adoption remains constrained by limited access to finance, inadequate infrastructure, and insufficient extension services. Similarly, agroecological approaches, including crop diversification, agroforestry, and organic farming, have proven successful in fostering sustainable agricultural practices and enhancing biodiversity, yet face significant challenges from prevailing agricultural policies and institutional frameworks that favor large-scale industrial agriculture. The study recommends scaling up the adoption of CSA and agroecology by improving access to financing, technology, and farmer training programs. It also advocates for policy reforms that support agroecological practices and climate adaptation, as well as increased investment in research and development. Additionally, fostering multi-stakeholder collaborations, including public-private partnerships, is critical to overcoming institutional barriers and ensuring the effective implementation of climate adaptation strategies. The conclusion underscores the need for integrated policy frameworks that combine the strengths of CSA and agroecology to build a resilient, sustainable, and food-secure agricultural sector in Africa. By addressing both environmental and socioeconomic challenges, these strategies can significantly contribute to combating the impacts of climate change on African agriculture, ensuring long-term food security and sustainable development.","本研究探讨了气候智能型农业（Climate-Smart Agriculture, CSA）和农业生态学在增强非洲农业应对气候变化韧性和粮食安全方面的作用。通过系统梳理现有文献、案例研究和政策框架，本研究考察了这些适应性策略在非洲大陆的实施情况并评估其有效性。研究发现，尽管气候智能型农业技术——如抗旱作物品种、节水灌溉和土壤管理措施——对提高农业生产力和韧性具有切实效益，但其广泛采用仍受限于融资渠道有限、基础设施不足和推广服务欠缺。同样，农业生态学方法，包括作物多样化、农林业和有机农业，已被证明在促进可持续农业实践和增强生物多样性方面卓有成效，但仍面临来自有利于大规模工业化农业的现行农业政策和制度框架的重大挑战。本研究建议通过改善融资渠道、技术获取和农民培训项目来扩大气候智能型农业和农业生态学的采用。研究还倡导支持农业生态实践和气候适应的政策改革，以及增加研发投入。此外，促进多方利益相关者合作，包括公私合作伙伴关系，对于克服制度障碍和确保气候适应策略的有效实施至关重要。结论强调，需要建立综合性政策框架，将气候智能型农业和农业生态学的优势相结合，以在非洲构建具有韧性、可持续且粮食安全的农业部门。通过同时应对环境和社会经济挑战，这些策略能够为抵御气候变化对非洲农业的影响、确保长期粮食安全和可持续发展作出重大贡献。","IIARD INTERNATIONAL JOURNAL OF GEOGRAPHY AND ENVIRONMENTAL MANAGEMENT","2026-09-21T00:00:00Z",{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":293},"系统综述非洲气候智慧型农业与生态农业的适应策略及政策障碍，结论可靠但属文献综述，非突破性成果。",[295],{"name":290,"url":287},[29,30,297,298,299],"气候智慧型农业","农业适应","生态农业",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[302,307],{"code":303,"slug":304,"name":305,"path":306,"parent_code":44},"H8","sustainable-agriculture","可持续与保护性农业","\u002Ftopic\u002Fenvironment\u002Fsustainable-agriculture",{"code":40,"slug":41,"name":42,"path":43,"parent_code":44},{"status":46,"locked":14,"version":47,"method":48,"evidence":309},{"candidates":310,"agricultural_evidence":52},[311,315,322,326,335,340,347,351,356],{"code":33,"score":59,"supported":52,"title":312,"abstract":313,"tags":314},[61],[29,61],[29],{"code":303,"score":316,"supported":52,"title":317,"abstract":319,"tags":321},12,[318],"sustainable agriculture",[320],"可持续农业",[299],{"code":40,"score":13,"supported":52,"title":323,"abstract":324,"tags":325},[],[56,31,54],[297],{"code":327,"score":119,"supported":52,"title":328,"abstract":329,"tags":334},"H6",[],[330,331,332,333],"生物多样性","农业生态","biodiversity","agroecology",[],{"code":240,"score":107,"supported":52,"title":336,"abstract":337,"tags":339},[],[338,244],"土壤",[],{"code":341,"score":107,"supported":52,"title":342,"abstract":343,"tags":346},"H3",[],[344,345],"灌溉","irrigation",[],{"code":80,"score":74,"supported":52,"title":348,"abstract":349,"tags":350},[],[30],[30],{"code":65,"score":241,"supported":52,"title":352,"abstract":353,"tags":355},[],[354],"smart agriculture",[],{"code":357,"score":241,"supported":52,"title":358,"abstract":359,"tags":361},"J1",[],[360],"农业政策",[],[363,364],"气候智慧型农业 非洲","生态农业 粮食安全","气候智慧型农业非洲-3156","10.56201\u002Fijgem.vol.11.no2.2025.pg8.32",{"doi":366,"openalex_id":368,"authors":369,"venue":290,"cited_by_count":22,"oa_url":9,"card":372,"direction":103,"ingested_from":104},"W7213982962",[370],{"name":371,"orcid":9},"Ayobami Samuel Owoyemi",{"tldr":373,"method":374,"finding":375,"direction":376,"opportunity":377},"综述气候智慧型农业与生态农业在非洲提升农业韧性与粮食安全的成效及障碍。","文献综述、案例研究与政策框架分析。","两类策略有效但受资金、基建、推广服务及政策偏向制约。","农业绿色发展与碳","可量化评估CSA与生态农业在非洲不同区域的适配性与政策协同效果。","2026-09-22T23:30:10.505058Z",{"id":380,"title":381,"url":382,"summary":383,"summary_zh":384,"content":9,"source_name":385,"source_url":382,"published_at":386,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":387,"score_detail":388,"sources":392,"tags":394,"primary_topic":397,"secondary_topics":398,"classification":404,"search_phrases":473,"slug":476,"view_count":22,"doi":477,"paper":478,"created_at":507},1380,"Harnessing Digital Twin (DT) Technology for Food Security and Climate Resilience in Sub-Saharan Africa (SSA)","https:\u002F\u002Fdoi.org\u002F10.1016\u002Fj.atech.2026.102532","Sub-Saharan Africa (SSA) faces chronic food insecurity despite possessing approximately 60% of the world’s uncultivated arable land. Field trials generate evidence but are costly and insufficiently scaled to address accelerating climate and demographic pressures. Digital twin (DT) technology, defined as the continuous, bidirectional virtual replication of physical systems using real-time data, supports monitoring, modelling, and optimisation of agrifood systems. To our knowledge, however, no published synthesis has examined DT agriculture research through the lens of SSA food systems or smallholder farming realities. A PRISMA-compliant systematic review was conducted across bibliographic databases using a pre-defined Boolean search and adapted PICOS eligibility criteria. Forty peer-reviewed studies published between 2019 and 2025 were included. Structured extraction captured bibliometric, geographic, methodological, technological, and technology readiness level (TRL) data, analysed using frequency tabulation and thematic clustering. DT agriculture publications roughly tripled between 2019 and 2023 (from three to ten studies), yet 57.5% of studies remain at TRL 2–3. Europe and East Asia dominate the evidence base; no study was led by an SSA institution, and no study reported SSA-based deployment on priority crops such as maize, cassava, sorghum, or cowpea. Internet of Things (IoT) sensor infrastructure (92.5%) and artificial intelligence\u002Fmachine learning (AI\u002FML) algorithms (52.5%) constitute the dominant technology stack. Five thematic clusters were identified: smart farming infrastructure, precision water and nutrient management, controlled environment agriculture, agrifood supply chains, and livestock and aquaculture systems. Government-funded studies tend to achieve higher TRL scores than academically funded counterparts. Synthesising these findings into a system-level, deployment-oriented analysis, we derive a conceptual SSA-DT framework. It combines offline-first edge-computing architecture, hybrid crop modelling, and multi-stakeholder interfaces, with dietary diversity and climate resilience as the two key performance indicators (KPIs), aligned with IITA’s 2024–2030 Strategy. North–South research partnerships and targeted CGIAR investment in DT technology are identified as priority actions for closing the SSA evidence gap.","撒哈拉以南非洲（SSA）尽管拥有全球约60%的未开垦耕地，却长期面临粮食不安全问题。田间试验虽能提供实证，但成本高昂且规模不足以应对日益加剧的气候与人口压力。数字孪生（DT）技术，定义为利用实时数据对物理系统进行持续、双向的虚拟复制，可支持农业食品系统的监测、建模与优化。然而，据我们所知，尚无已发表的综述从SSA粮食系统或小农生产现实的角度审视DT农业研究。本研究遵循PRISMA规范，在书目数据库中采用预定义的布尔检索和适应性PICOS资格标准进行系统综述，纳入2019至2025年间发表的40篇同行评审研究。结构化提取涵盖文献计量、地理、方法、技术及技术就绪水平（TRL）数据，并采用频次制表和主题聚类进行分析。DT农业出版物在2019至2023年间约增长两倍（从三篇增至十篇），但57.5%的研究仍处于TRL 2–3级。欧洲和东亚主导了证据基础；没有一项研究由SSA机构牵头，也没有研究报告在SSA地区针对玉米、木薯、高粱或豇豆等优先作物进行部署。物联网（IoT）传感器基础设施（92.5%）和人工智能\u002F机器学习（AI\u002FML）算法（52.5%）构成主导技术栈。研究识别出五个主题聚类：智慧农业基础设施、精准水肥管理、受控环境农业、农业食品供应链以及畜牧和水产养殖系统。政府资助的研究往往比学术资助的研究达到更高的TRL评分。将这些发现综合为系统层面、面向部署的分析，我们提出了一个概念性的SSA-DT框架。该框架结合离线优先的边缘计算架构、混合作物建模和多利益相关方接口，以膳食多样性和气候韧性作为两项关键绩效指标（KPI），与国际热带农业研究所（IITA）2024–2030年战略保持一致。南北研究伙伴关系和CGIAR对DT技术的定向投资被确定为缩小SSA证据差距的优先行动。","Smart Agricultural Technology","2026-09-01T00:00:00Z",79,{"impact":17,"substance":389,"depth":390,"authority":20,"freshness":66,"relevant":22,"comment":391},22,19,"系统综述数字孪生技术在撒哈拉以南非洲的应用，揭示研究空白并提出框架，对全球农业信息化有参考价值。",[393],{"name":385,"url":382},[27,395,29,396],"非洲","数字孪生",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[399,400],{"code":40,"slug":41,"name":42,"path":43,"parent_code":44},{"code":73,"slug":401,"name":402,"path":403,"parent_code":134},"agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai",{"status":46,"locked":14,"version":47,"method":48,"evidence":405},{"candidates":406,"agricultural_evidence":52},[407,412,417,421,427,432,439,446,453,460,467],{"code":65,"score":390,"supported":52,"title":408,"abstract":410,"tags":411},[409],"digital twin",[27,396,409],[396,27],{"code":40,"score":143,"supported":52,"title":413,"abstract":415,"tags":416},[414],"climate resilience",[414],[],{"code":33,"score":119,"supported":52,"title":418,"abstract":419,"tags":420},[61],[],[29],{"code":73,"score":119,"supported":52,"title":422,"abstract":423,"tags":426},[],[424,425,77],"机器学习","machine learning",[],{"code":130,"score":119,"supported":52,"title":428,"abstract":429,"tags":431},[],[155,430,156,157],"边缘计算",[],{"code":433,"score":107,"supported":52,"title":434,"abstract":435,"tags":438},"A3",[],[436,437],"玉米","maize",[],{"code":440,"score":107,"supported":52,"title":441,"abstract":442,"tags":445},"A5",[],[443,444],"高粱","sorghum",[],{"code":447,"score":107,"supported":52,"title":448,"abstract":449,"tags":452},"C",[],[450,451],"畜牧","livestock",[],{"code":454,"score":107,"supported":52,"title":455,"abstract":456,"tags":459},"D",[],[457,458],"水产","aquaculture",[],{"code":461,"score":107,"supported":52,"title":462,"abstract":463,"tags":466},"I7",[],[464,465],"文献计量","bibliometric",[],{"code":468,"score":241,"supported":52,"title":469,"abstract":470,"tags":472},"G2",[],[471],"smallholder",[],[474,475],"数字孪生 智慧农业 粮食安全 非洲","数字孪生 智慧农业","数字孪生智慧农业粮食安全非洲-1380","10.1016\u002Fj.atech.2026.102532",{"doi":477,"openalex_id":479,"authors":480,"venue":385,"cited_by_count":95,"oa_url":500,"card":501,"direction":505,"ingested_from":104},"W7204898011",[481,484,486,489,491,494,496,498],{"name":482,"orcid":483},"Henri E.

Smallholder agriculture is the bedrock of Zimbabwe's food system, yet it remains highly vulnerable to a complex array of shocks and stressors. Using a mixed-methods approach, this research investigates the prevalence, drivers and lived experiences of food insecurity within this community. A structured survey was administered to 412 randomly selected smallholder households across the district's wards. The quantitative data were supplemented by 12 Focus Group Discussions (FGDs) and 24 Key Informant Interviews (KIIs) with farmers, community leaders and agricultural extension officers to capture qualitative nuances. The study is grounded in the Food Security Theory (FST), which conceptualises food security through its four pillars: food availability, food access, food utilisation and food stability. Findings reveal a precarious food security situation. Quantitatively, 78.4% of households were found to be food insecure, with an average Hunger Months Index of 4.7 months per year. The study identifies a significant disconnect between maize production, the national staple and household consumption, with over 65% of households failing to produce enough maize to meet their annual requirements. Qualitative data illuminated the multi-faceted drivers of this insecurity. Key points to note include climate change whereby erratic rainfall and prolonged mid-season dry spells were consistently reported as the primary production challenges, limited access to farming inputs whereby high costs and unreliable supplies of certified seeds, fertilizers and agro[1]chemicals constrain productivity. Morelso, socio-economic factors such as poverty, lack of viable alternative livelihoods and limited access to formal credit perpetuate a cycle of vulnerability. In addition, institutional weaknesses, for example, challenges with agricultural extension services and market inefficiencies, exacerbate the situation. The study concludes that food insecurity in Zvimba is not merely a problem of food production, but is deeply rooted in structural issues affecting food access, food utilisation, as well as food stability. Recommendations are proposed for a multi-sectoral approach, including promoting Climate-Smart Agriculture (CSA) and drought-resistant crops, strengthening input support systems and rural finance, diversifying livelihood strategies and enhancing the capacity of extension services. This research contributes to a deeper understanding of the localised dynamics of food security and provides evidence-based guidance for policymakers, development practitioners and the farmers of Zvimba themselves.","本研究对津巴布韦兹维姆巴区小农户（smallholder farmers, SHFs）的粮食安全状况进行了全面分析。小农农业是津巴布韦粮食体系的基石，但仍极易受到一系列复杂冲击和压力的影响。本研究采用混合方法，考察了该社区粮食不安全的普遍程度、驱动因素及生活体验。研究对该区各选区随机抽取的412户小农户进行了结构化问卷调查。定量数据辅以12次焦点小组讨论（FGDs）和24次关键知情人访谈（KIIs），访谈对象包括农民、社区领袖和农业推广人员，以捕捉定性层面的细微差异。本研究以粮食安全理论（Food Security Theory, FST）为基础，该理论通过四大支柱界定粮食安全：粮食可供性、粮食获取、粮食利用和粮食稳定性。研究结果揭示了严峻的粮食安全形势。定量数据显示，78.4%的家庭存在粮食不安全，年均饥饿月份指数为4.7个月。研究发现，玉米产量——该国主粮——与家庭消费之间存在显著脱节，超过65%的家庭生产的玉米不足以满足其年度需求。定性数据揭示了这一不安全状况的多重驱动因素。值得注意的要点包括：气候变化，即降雨不稳定和持续的中期干旱被一致报告为主要生产挑战；农业投入品获取受限，即认证种子、化肥和农用化学品成本高昂且供应不可靠，制约了生产力。此外，贫困、缺乏可行的替代生计以及正规信贷获取受限等社会经济因素使脆弱性循环持续存在。此外，制度薄弱环节，例如农业推广服务面临的挑战和市场效率低下，加剧了这一状况。研究得出结论，兹维姆巴的粮食不安全不仅仅是粮食生产问题，而是深深植根于影响粮食获取、粮食利用以及粮食稳定性的结构性问题。研究提出了采取多部门方法的建议，包括推广气候智能型农业（Climate-Smart Agriculture, CSA）和抗旱作物、加强投入品支持体系和农村金融、多样化生计策略以及增强","Ngenani The Zimbabwe Ezekiel Guti Journal of Community Engagement and Societal Transformations","2026-10-20T00:00:00Z",55,{"impact":21,"substance":17,"depth":59,"authority":107,"freshness":21,"relevant":22,"comment":518},"基于412户调查与混合方法的扎实实证研究，但属津巴布韦地方性案例，公共影响与信源权威度有限，可作参考而非每日精选。",[520],{"name":514,"url":511},[29,522,523,524,525],"小农户","气候智慧农业","农业推广","津巴布韦",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[528,533],{"code":468,"slug":529,"name":530,"path":531,"parent_code":532},"farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",{"code":40,"slug":41,"name":42,"path":43,"parent_code":44},{"status":46,"locked":14,"version":47,"method":48,"evidence":535},{"candidates":536,"agricultural_evidence":52},[537,541,545,549,555,559,566],{"code":33,"score":59,"supported":52,"title":538,"abstract":539,"tags":540},[61],[29,61],[29],{"code":468,"score":59,"supported":52,"title":542,"abstract":543,"tags":544},[471],[522,471],[522],{"code":40,"score":13,"supported":52,"title":546,"abstract":547,"tags":548},[],[56,150,54,210],[523],{"code":550,"score":66,"supported":52,"title":551,"abstract":552,"tags":554},"G1",[],[524,553],"agricultural extension",[524],{"code":433,"score":107,"supported":52,"title":556,"abstract":557,"tags":558},[],[436,437],[],{"code":560,"score":107,"supported":52,"title":561,"abstract":562,"tags":565},"G3",[],[563,564],"农村金融","rural finance",[],{"code":65,"score":241,"supported":52,"title":567,"abstract":568,"tags":569},[],[354],[],[571,572],"Zvimba 小农户 粮食安全","津巴布韦 小农 玉米","Zvimba小农户粮食安全-5478","10.71458\u002Frx0qpm30",{"doi":574,"openalex_id":576,"authors":577,"venue":514,"cited_by_count":95,"oa_url":9,"card":586,"direction":103,"ingested_from":104},"W7223029383",[578,581,584],{"name":579,"orcid":580},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":582,"orcid":583},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":585,"orcid":9},"Patience Mutopo",{"tldr":587,"method":588,"finding":589,"direction":505,"opportunity":590},"调查津巴布韦Zvimba小农户粮食安全状况，分析其普遍性、成因与实际体验。","混合方法：412户问卷、12场焦点小组、24个关键人物访谈，基于粮食安全四支柱理","78.4%家庭粮食不安全，年均饥饿月4.7个月，主因是气候、投入、社会经济与制度等结构性问题。","可探索用移动端问卷与遥感产量监测构建小农户粮食安全动态预警与精准干预系统。","2026-10-21T23:30:08.937079Z",{"id":593,"title":594,"url":595,"summary":596,"summary_zh":597,"content":9,"source_name":598,"source_url":595,"published_at":599,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":600,"score_detail":601,"sources":604,"tags":606,"primary_topic":609,"secondary_topics":610,"classification":613,"search_phrases":670,"slug":673,"view_count":95,"doi":674,"paper":675,"created_at":687},5185,"When the rains are too much: El Niño, Smallholder Farmers and Food Security in Western Kenya","https:\u002F\u002Fdoi.org\u002F10.18697\u002Fajfand.155.ed182","When the rains are too much: El Niño, Smallholder Farmers and Food Security in Western Kenya For generations, farmers in Western Kenya have watched the skies carefully. The arrival, duration, and distribution of rainfall have traditionally provided important signals about when to prepare land, plant, weed, and harvest. But these signals are becoming increasingly difficult to read. Climate change is altering rainfall patterns, while increasingly frequent extreme weather events are making farming more uncertain. The current outlook for the October–December 2026 season brings this challenge sharply into focus. The IGAD Climate Prediction and Applications Centre (ICPAC) forecasts a wetter-than-normal season across much of the Greater Horn of Africa. The Lake Victoria Basin, which includes large parts of Western Kenya, is among the areas with a high likelihood of receiving more than 400 mm of seasonal rainfall. ICPAC reports that El Niño has developed and is expected to strengthen, while a positive Indian Ocean Dipole is also expected—climate conditions that are commonly associated with enhanced rainfall in the region, and is likely to run into February of 2027. But what does this mean for the smallholder farmer? The first point is that more rainfall does not necessarily mean more food. For a farmer whose livelihood depends almost entirely on rain-fed agriculture, abundant rainfall can be a blessing. It can replenish streams and water sources, improve soil moisture, restore pasture and create favourable conditions for crop production. If well distributed, the rains could contribute to improved harvests and household food supplies. The problem arises when rainfall is too intense, too concentrated or poorly distributed. A farmer may receive a great deal of rain in a few days and then experience a dry spell. Another farmer a few kilometres away may receive considerably less. Heavy downpours can cause flooding, waterlogging and soil erosion. Seeds may be washed away soon after planting. Young crops can be submerged or damaged. Valuable topsoil and nutrients can be carried away, reducing the productivity of land in subsequent seasons. This is particularly important in Western Kenya, where many households depend on small parcels of land for both food and income. A failed or damaged crop is not simply an agricultural loss. It can mean less food in the household, less money for school fees and health care, and fewer resources to purchase nutritious foods. The food-security paradox We must, therefore, look beyond agricultural production to food and nutrition security. A household may produce enough maize yet still have a poor diet if vegetables, legumes, fruits, milk, eggs or other foods are unavailable or unaffordable. Climate shocks can reduce this diversity. When crops are damaged, families may depend more heavily on whatever staple food remains available. This is why climate resilience must also be nutrition-sensitive. Western Kenya has a rich agricultural tradition and considerable potential for diversified food production. Farmers grow cereals, legumes, vegetables and root crops and keep livestock and poultry. Such diversity is not merely an agricultural advantage; it is a nutritional resource. It can provide different foods, spread risk and generate income at different times of the year. Climate adaptation should, therefore, not encourage farmers simply to produce more of one crop. It should help them build diverse and resilient farming systems. Women carry a large part of the burden The impact of erratic and excessive rainfall also has a gender dimension. Women in smallholder households are often deeply involved in food production, processing, preparation and household nutrition. When harvests fail, or food prices rise, women frequently have to find ways of stretching limited household resources to feed the family. When roads become impassable or markets are disrupted, women may have greater difficulty accessing food and agricultural inputs. When water sources are contaminated or damaged, household responsibilities can become even more demanding. Climate adaptation must therefore deliberately include women—not simply as beneficiaries, but as decision-makers, innovators, farmers and leaders. Young people must also be part of the solution There is another group that deserves greater attention: young people. Western Kenya cannot build climate-resilient agriculture while treating agriculture as an occupation of the past. Young people need to see opportunities in modern farming, agro-processing, food safety, climate information services, irrigation, digital agriculture and agricultural entrepreneurship. The increasing unpredictability of climate may actually provide an opportunity to make agriculture more innovative. Young people can help introduce new technologies, improve access to climate information, develop value-added products and create businesses around food production and processing. From forecasting to action The availability of a climate forecast is useful only if it reaches the people who need it in time. Farmers need information that answers practical questions: When should I plant? Which crops or varieties are appropriate? How can I protect my soil? What should I do if rainfall becomes excessive? How can I protect harvested food? Where can I obtain reliable seed and other inputs? Seasonal forecasts should, therefore, be translated into local, practical agricultural advice. ICPAC itself emphasizes that seasonal forecasts should be used together with weekly and monthly forecasts and national meteorological information. This requires stronger links between meteorological services, agricultural extension officers, researchers, county governments, farmer organizations and communities. We should also strengthen simple but important measures: water harvesting, drainage, terracing and soil conservation; planting crops and varieties suited to local conditions; maintaining vegetation cover; diversifying crops and livestock; improving storage facilities; and protecting food from moisture and contamination. Prepare before the rain comes The greatest lesson from the current El Niño outlook is perhaps that preparedness must begin before the first heavy rains arrive. Governments and development partners should not wait for floods, damaged roads, destroyed crops or food shortages before responding. Early warning should lead to early action. Farmers should be supported to prepare their farms, protect livestock, secure seed and inputs, strengthen food storage and identify alternative routes to markets. This is particularly important because the same season can produce both opportunities and losses. ICPAC notes that enhanced rainfall can support agricultural production and replenish water resources, but can simultaneously increase the risk of flooding, flash floods and landslides in vulnerable areas. A changing climate requires a different agricultural mindset Perhaps the most important change we need is in the way we think about farming. For too long, agricultural planning has often assumed that rainfall will behave according to a familiar calendar. That assumption is becoming increasingly unsafe. Farmers now have to manage not only too little rain, but also too much rain, rain at the wrong time and rain in the wrong place. The challenge is, therefore, not simply to produce more food. It is to build food systems that can continue providing adequate, diverse, safe and nutritious food under increasingly uncertain climatic conditions. Western Kenya's smallholder farmers should not be left alone to carry this burden. They need science that responds to their realities, extension services that reach them, climate information they can understand and use, financial services that help them manage risk, markets that function during difficult seasons, and policies that recognize the central role of smallholder agriculture in national food and nutrition security, and partners who are willing to appreciate and make use of indigenous knowledge. El Niño should, therefore, be viewed neither simply as a disaster nor automatically as a blessing. It is a climate event whose consequences will depend greatly on our preparedness. The question before us is not merely, “Will the rains come?” They probably will. The more important question is: Will our farmers, food systems and institutions be ready when they do? That is where climate resilience—and ultimately food and nutrition security—will be tested.
